直升机蒸气循环制冷系统技术现状与展望

笔者主要从舱内环境控制方面 ,分析了高温对直升机飞行安全的影响 ,指出了直升机安装制冷系统的必要性 ,同时对国外现役直升机采用的两种制冷系统即蒸气循环制冷系统与空气循环制冷系统进行了性能对比。在此基础上 ,提出我国发展直升机制冷系统的主推方案是蒸气循环制冷系统 ,并对我国进行直升机蒸气循环制冷系统研究的技术关键和发展方向给予展望 ,为我国开展此领域的科学研究和技术创新提供一定的技术储备。

Current Status and Perspective of Cooling System of Helicopter Using Steam Cycling Technique

From point of view of environment control system in cabin, the impact of high temperature on flight safety of helicopter was analyzed. The necessity to install cooling system on helicopter was stated. By comparing the performance of steam cycling cooling system with air cycling cooling system, the former system would be preferred as the main protocol in China in future. The prospect of research of this technique was described, which could be taken as the technical preparation for future study in China.
